Crushed glass

Broken glass is a type of safety glass that holds together when shattered. In the event of breakage, it is held in place by an interlayer, typically of , between its two or more layers of glass. The interlayer keeps the layers of glass bonded even when broken, and its high strength prevents the glass from breaking up into large sharp pieces. This produces a characteristic "spider web" cracking pattern when the impact is not enough to completely pierce the glass. Broken Laminated glass is normally used when there is a possibility of human impact or where the glass could fall if shattered. Shopfront glazing and are typically laminated glasses. The PVB interlayer also gives the glass a much higher rating, due to the damping effect, and also blocks 99% of transmitted UV light. Thanks to it that when it is broken, it will not fly off and can hardly hurt people, only bringing about radiation-like crack because of the stickiness effect caused by the glass, Laminated glass has more shock resistance capability than the common glass has and can hardly be broken when impacted, so it is widely used in the front windows of automobile and is a safety glass against theft.
